But wide receiver Michael Calvin, needing an impressive effort to get on the radar of scouts, coaches and executives, did just that in heavy rain Wednesday morning.
Calvin was timed running the 40-yard dash in the low 4.3s, a blistering time given the waterlogged conditions on Witter Rugby Field, preventing individual position drills from being conducted.
Wearing neon green track shoes – "I wanted you guys to look at how fast my feet were moving," he joked – a sculpted Calvin blazed past a group of two dozen NFL representatives.
"When I got to the end of the field and they were all just staring at me, comparing the times and trying to make sure it was a consistent time. It was a good thing to see because it obviously means I ran something fast," Calvin said.
Calvin also had a 40.5-inch vertical jump, but was disappointed he did not have a chance to run routes and catch passes. He said he would consult with his agent and could set up workouts at a later date.
"All the stuff on paper looks great, but I know these guys out here want to see what you can do as far as position work goes," he said.
The Bears' third receiver behind Jones and sophomore Keenan Allen, Calvin only caught 42 passes for 528 yards and one touchdown in his college career but his athleticism will certainly now get him into a camp, if not drafted.
"This is a chance for me to actually show the assets I have," Calvin said. "Being under the radar, it's good to get this kind of exposure."
The other standout was defensive end Ernest Owusu, who bench pressed 225 pounds 39 times. Memphis defensive tackle Dontari Poe posted the top mark at the combine with 44 reps.
Even though they did not run, Kendricks and Jones drew the most media attention afterwards.
Regarded as second day picks, Jones and Kendricks declined to say what teams they will meet with t in the run-up to draft, set for April 26-28, though Kendricks did disclose he has nine visits scheduled.
Both are pleased with what the interest they are receiving.
"I have definitely boosted my stock sky high from where I was," said Jones, who impressed at the Senior Bowl in Mobile, Ala. "I've heard a lot of things, a solid second-round at worst."
Said a coy Kendricks said: "I've got some people looking at me."
